Primary Outcome Measures
NameTimeMethod
Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - 8)]6 days

AUC (0 - 8)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - 8). It is obtained from AUC (0 - t) plus AUC (t - 8).

Maximum Observed Plasma Concentration (Cmax)6 days
Secondary Outcome Measures
NameTimeMethod
Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)6 days

Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)

Apparent Oral Clearance (CL/F)6 days

Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Clearance was estimated from population pharmacokinetic (PK) modeling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

Time to Reach Maximum Observed Plasma Concentration (Tmax)6 days
Apparent Volume of Distribution (Vz/F)6 days

Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.

Plasma Decay Half-Life (t1/2)6 days

Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.
